Reinforced Concrete for the Construction Stage of an Incrementally Launched Bridge
This article discusses the 375m long incrementally launched bridges over the Usuthu River using reinforced concrete, with no pre-stressing, to carry the construction stage loads.
Utilizing Compressible Inclusions and Cement Stabilised Sand for Integral Bridges
Bridges are designed to function for 100 years but often the costs of maintenance are very significant. Bearings and expansion joints which affect the performance of a bridge are mainly the source of maintenance cost. In this case, an integral…
Structural and Risk Assessment of Steel and Concrete Bridges using Inservice Dynamic Response
Mainmark are introducing the STRAAM system of full scale structural integrity assessment and continuous monitoring for Bridges into Australia and New Zealand. Advances in measuring extremely low amplitude vibrations combined with methods for…
Ambitions, Durability Risks and Asset Protection: Literature Review and Learning from Relevant Cases of Existing Bridge Structures
All reinforced concrete structures deteriorate over time. Corrosion of reinforcement is a major challenge to the durability of concrete structures. Corrosion in certain environments, such as marine, can compromise the durability of concrete and…
Destructive Load Testing of Transversely Stressed Deck Unit Bridges
As part of the NACOE research project ‘Deck unit bridge deck analysis under live load’, a comprehensive load testing program has been conducted in Queensland to investigate the behaviour of transversely stressed precast prestressed concrete deck…
Improving Corrosion Resistance of Reinforced Concrete Structures Using Carbon Fibre Reinforced Polymer
Corrosion of steel is regarded as one of the most important issues for the durability of reinforced concrete (RC) structures, as corrosion can induce the serviceability decrease, bond strength dropping, steel properties reduction, and longitudinal…
Chloride Ingress and Steel Corrosion in Slag and Fly Ash Blended Geopolymer Concrete
Alkali activated binders (geopolymer) is an emerging technology to produce concrete without the use of any Ordinary Portland Cement (OPC) by alkali activation of alumino-silicate source materials such as fly ash and/or slag. Limited knowledge on…
Establishing Positive Moment Continuity in Prestressed Concrete Girder Bridges: Performance and Lessons Learned
Structural health monitoring (SHM) is employed to evaluate a prestressed concrete bridge continuity detail in a newly constructed bridge in Louisiana. The detail is capable of resisting positive continuity moments that develop due to long-term and…
Investigation the Influence of FRP Application Performance on Fatigue Life Behavior of CFRP Laminates Bonded to Concrete Block
In this paper, two methods of FRP applications were carried out to study the fatigue life performance of CFRP laminates bonded to RC concrete block, by mean of investigating the influence of bond behavior application under cyclic loadings.

  • Bridges
Munna Point Bridge was built in Noosa Heads, Queensland in the late 1970s. Over 1.8 million trips in each direction are made across the 106 metre bridge every year, by tourists and locals. The bridge is one of only two routes to reach the primary…
